  • Destroys through card effect, preventing effects that activate when destroyed by battle.
  • You won't take damage if you use its effects since the monster is destroyed before damage calculation.


  • Average attack and defense.
  • Effect is only useful if your opponent has defense position monsters.
  • Does not get around flip effects.


  • Effect would also work when attacking face-down monsters because they are flipped face-up first before the effect activates.
  • If a defense position monster’s effect activates when it is destroyed as a result of battle, you can attack it with Drillroid to destroy it with a card effect instead so that it’s effect does not activate.
  • Can be used to destroy defense position monsters that cannot be destroyed by battle.

Change Battle Position

Use cards that can change your opponent’s monsters to defense position making them vulnerable to Drillroid’s effect. These cards could also be used as protection during your opponent’s battle phase.

To defense

There are numerous ways to switch your opponent's monster to defense position, and many are easy to obtain cards outside of buying packs like Enemy Controller. This makes Drillroid a versatile card that can be put in many different decks since cards to switch to defense like Windstorm and Enemy Controller are common in most decks.

Some of the machine support cards are incredibly useful, making him fit well with a full machine type deck.

  • Pulse Mines switches all monsters your opponent controls to defense, as well any other monsters they might summon in the turn. This is really good since you can activate it when your opponent targets it with cards like Sergeant Electro, or Storm and it will still work on monsters they would summon.
  • Rare Metalmorph will let you negate a spell card that targets your monster, and also increases your attack. This is commonly used to negate Enemy Controller since most deck has 1 or more copies of it in the deck.
  • Gravity Blaster is to negate monster effects, including flip effects, and increase attack. It's a good support card to have for a machine deck.
  • Sergeant Electro locks your opponent's backrow so you can safely attack.

First the flip effect happens and only then DrillRoid's effect activates.

No, the opposing face-down monster is flipped face-up first, THEN Drillroid's effect is applied.

That's the official ruling.

Since the opposing monster is flipped face-up first, any effect the opposing monster has when flipped face-up, will activate, and form a chain, with the opposing monster's effect at CL2 and thus resolves first.

Drillroid's effect is applied during the tiny window after the opposing monster is flipped face-up, but before damage calculation.

That's why this thing is NOT a Komushroomo counter lol

Isn't that the whole point of drillroid not to flip the mushroom and destroy it before the effect can be triggered

No, Drillroid flips the opponent's monster up first.

It's the official ruling for it and it is also what happens in DL, I've personally tested it.

And is also just how those kinds of effects work in general. If it destroyed them without flipping them face-up, it would say it destroyed them at the start of the Damage Step (which is the only part of the Damage Step before they're face-up). There are cards like Sasuke Samurai and the Mystic Swordsman monsters if you are actually after that kind of effect.

Maybe this is why Syrus is coming before Zane? To help people get rid of that mushroom? Lol
Nah Konami won't release it, it would be too good in DL right now and we can't have that
Bye-bye Sylvan
